The Benefits of Sweet Potato for Dogs
Sweet potato is one of nature's most nutritious vegetables, and dogs love it. It's naturally rich in fibre, which supports healthy digestion, and provides a range of important nutrients including B vitamins, potassium, magnesium, and calcium. It's also low in fat, making it an ideal base for a healthy dog biscuit recipe.
When paired with the slow-release energy of oats, a whole grain that contains beta-glucan, a soluble fibre that supports healthy cholesterol and steady blood sugar levels, you've got a treat that's genuinely good for your dog, not just tasty.
The egg helps bind everything together, while the stock gives the dough a flavour dogs find irresistible.
A quick note: these biscuits are intended as an occasional treat, not a meal replacement. As with any addition to your dog's diet, always consult your vet before making changes, particularly if your dog has an existing health condition or food sensitivity.
What You'll Need
This sweet potato dog treat recipe makes approximately 30-40 biscuits, depending on the size of your cutter. We'd recommend a 7-10cm bone-shaped cutter for that classic look, but any shape works just as well.
Ingredients
- 1 large sweet potato, peeled, boiled and mashed
- 250g of plain flour (plus extra for dusting)
- 180g of rolled oats
- 1 egg
- Up to 500ml of low-salt chicken, beef, or vegetable stock
Tip: If your dog has a sensitive stomach or known allergies, vegetable stock is the most neutral option.
How to Make Sweet Potato Dog Biscuits
Step 1: Prep your sweet potato
Peel and chop the sweet potato into small chunks, then boil for around 10 minutes until completely soft. Drain, mash thoroughly, and set aside to cool. It's important that the mash isn't warm when you add the other ingredients, or it may start to cook the egg.
Step 2: Preheat your oven
Set your oven to 180°C (160°C fan) or gas mark 4. Line a baking tray with parchment paper and set aside.
Step 3: Mix your dry ingredients
In a large mixing bowl, lightly beat the egg. Stir in the flour and oats until combined.
Step 4: Bring the dough together
Add the cooled sweet potato mash to your flour and oat mixture. Gradually pour in around 250ml of stock, stirring as you go, until a firm dough forms. You're looking for a consistency that holds its shape without sticking to your hands. If it's too sticky, add a little more flour. If it crumbles, add a splash more stock.
Step 5: Roll and cut
Lightly flour your work surface, then roll the dough to about 1-1.5cm thick. Cut out your biscuits with your chosen cutter, then place them on the prepared baking tray, leaving a little space between each.
Step 6: Bake
Pop the tray into your preheated oven and bake for 25-35 minutes, until the biscuits are firm, golden, and crisp all the way through. The longer they bake within this window, the crunchier and longer-lasting they'll be.
Step 7: Cool completely
Transfer the biscuits to a wire rack and allow them to cool fully before giving them to your dog. Warm biscuits may be soft in the middle. Cooling ensures they crisp up properly.
